Setting the oven thermostat minimum
To set the minimum, proceed as follows:
open the over door;
light the oven burner and set it to maximum, close the door and wait for about 10 minutes
(or the time required for the oven to heat up to about 230°C);
remove the oven knob and, using the hole in the control panel, according to the
thermostat type (Fig. C), loosen the by-pass screw of the thermostat by two turns;
replace the knob and turn it to the minimum position, remove the knob and adjust the
previously loosened screw until the flame is lowered but stable, even when rapid
changes from maximum to minimum are made and the oven door is opened or closer
quickly.
N.B. For liquid gas setting, the oven burner minimum is set by fully tightening the
thermostat by-passes.
Gas grill burners
To convert the gas to this type of burner, see the "oven burner" instructions above. The only
difference is that the burner is in the top of the oven, and there is no need to set the minimum
because the burner always works at full power.
2. MAINTENANCE
WARNINGS:
Before carrying out any maintenance or conversion operations, turn off the electricity
supply and close the gas upstream of the appliance. If components and/or
accessories need replacing, use only Lofra spare parts only. All the operations
hereunder must be carried out by qualified technicians in accordance with the
enclosed instructions and current installation standards.
Before replacing the bulb, disconnect the unit from the electricity supply and, if
recently used, make sure that the oven has cooled down
The oven must be switched off before taking the filter off.
2.1. GAS SUPPLY RUBBER PIPE
The condition of the gas supply pipe should be checked periodically (once a year) and replaced
by the date printed on the outside of the pipe and if there are signs of cracking, cuts, scratches
or burns, or if it is no longer flexible but hard and plastic. The pipe must be suitable for use with
liquid gas and comply with the applicable standards.
2.2. ELECTRICITY SUPPLY CABLE
If the electricity supply cable needs replacing, therefore only authorised LOFRA technicians
may replace it. Use HO5FVV-F cables only. The earth wire (yellow/green) must be at least 2 cm
longer than the other two phase wires (fig. 5 B). This ensures that the electrics are safe should
the wire be pulled accidentally.
For the cookers with a gas oven and an electric grill, use a 3x1,5 mm² HO5RR-F cable, for
cookers with electric oven and grill, use a 3x1.5 mm² HO5VV-F cable with a maximum external
diameter of 9 mm. In the case of current exceeding 16A shall have the power section 2.5 mm²
(with UK plug the current not exceeded 13 A).
